Methods GeomConvert::ConcatG1, GeomConvert::ConcatC1, Geom2dConvert::ConcatG1, Geom2dConvert::ConcatC1 are corrected to prevent exceeding maximum degree of BSpline curve in case of closed contour.
Deprecated functionality related to Local Context has been removed.
The following classes and types have been removed:
AIS_LocalContext, AIS_DataMapOfILC, AIS_LocalStatus, SelectMgr_SequenceOfSelector, SelectMgr_DataMapOfObjectSelectors.
Value AIS_DS_Temporary has been removed from enumeration AIS_DisplayStatus.
The following methods related to Local Context have been removed from AIS_InteractiveContext:
::HasOpenedContext(), ::HighestIndex(), ::LocalContext(),
::LocalSelector(), ::OpenLocalContext(), ::CloseLocalContext(),
::IndexOfCurrentLocal(), ::CloseAllContexts(), ::ResetOriginalState(),
::ClearLocalContext(), ::UseDisplayedObjects(), ::NotUseDisplayedObjects(),
::SetShapeDecomposition(), ::SetTemporaryAttributes(),
::ActivateStandardMode(), ::DeactivateStandardMode(), ::KeepTemporary(),
::SubIntensityOn(), ::SubIntensityOff(),
::ActivatedStandardModes(), ::IsInLocal()
and ::AddOrRemoveSelected() taking TopoDS_Shape.
The methods AIS_InteractiveContext::Display() and ::Load()
taking argument theToAllowDecomposition have been marked as deprecated;
the new methods without this unused argument should be used instead.
AIS_InteractiveContext::DisplayedObjects() - removed argument theOnlyFromNeutral.
SelectMgr_SelectionManager has been simplified so that now it support only single Viewer Selector.
The argument -local has been removed from Draw Harness commands vselmode, vremove, vdisplay, vdisplayall, verase.
Implementation of the method for simplification of the result of Boolean Operation on the API level.
The method BRepAlgoAPI_BuilderAlgo::SimplifyResult has been added, so the derived classes such as BooleanOpeation and Splitter can also use this method.
The result shape simplification should be called after the operation is done. The simplification is performed by the means of ShapeUpgrade_UnifySameDomain algorithm.
Draw command "bsimplify" has been added to control the simplification options.
Documentation for new functionality and draw commands controlling the options of Boolean operations.
Test cases for the new functionality.
Side-effect change:
The algorithms in Boolean component have been changed to use the BRepTools_History as a History tool.
Now it became possible to disable the collection of shapes modifications during Boolean Operations, which may be useful for performance sake (in draw the option is controlled by *setfillhistory* command).
Draw command "unifysamedom" has been changed to accept the angular tolerance in degrees instead of radians.
1. Extrema algorithm calls Curve-surface intersector. This intersector returns flag about infinite solution (in spite of extrema's returning not-parallel status correctly - axes of considered cylinder and circle are not parallel). In this case, attempt of obtaining number of intersection points leads to exception.
So, the fix adds check of infinite solution after the intersection algorithm.
2. The methods IsDone(), IsParallel(), NbExt(), SquareDistance() and Points() (of Extrema_* classes) have been corrected to make them consistent to the documentation.
3. Revision of some Extrema_* classes has been made in order to avoid places with uninitialized variables.
4. Currently Extrema does not store any points in case when the arguments are parallel. It stores the distance only.
5. Some cases on Extrema-algo have been moved from "fclasses"-group to "modalg"-group.
Substitution of degenerated edges by their copies is implemented to make edges not shared
in BRepPrimAPI_MakeRevol::Build().
Method BRepPrimAPI_MakeRevol::Generated(...) is changed in order to use history of substitutions.
Test case is added.
Information on replacement of CDM_MessageDriver by Message_Messenger is added in the upgrade guide.
This replacement is recorded as rename in upgrade.dat
The API classes in the package BRepAlgo providing access to old Boolean operations (Fuse, Common, Cut, Section) are marked as deprecated.
Corresponding classes from the package BRepAlgoAPI should be used instead.
When checking if the split edge is oriented as the original one (BOPTools_AlgoTools::IsSplitToReverse()) the tangent vectors should be computed for both edges at the same point. This point is taken on the split edge and projected on the original edge.
The fix is intended to ensuring that the reference point will be taken inside the valid range of the split edge (i.e. not covered by the tolerance spheres of its bounding vertices) and the projection of this point on the original edge will be successful. Moreover, several sampling points are now taken on the split edge and processed until first valid point is found.
If requested (by a not null pointer) all *BOPTools_AlgoTools::IsSplitToReverse()* methods are now return the error status of the check. Before using the returned flag, the calling program should check this error status. For successful check the error status should be equal to zero.
New warning *BOPAlgo_AlertUnableToOrientTheShape* is now returned in the algorithms in Boolean component in case the check for correct shape orientation failed.
Test case for the issue.
- BUILD_SAMPLES_MFC instead of BUILD_MODULE_MfcSample
- BUILD_SAMPLES_QT instead of BUILD_MODULE_QtSample
- sub-folder "mfc" of Samples folder in VStudio for mfc samples
- qt processing of *.ts resource files is corrected to avoid excessive projects creation under Samples folder in VStudio
Boolean Operation - avoid creation of INTERNAL solid from unclassified faces in Solid Builder algorithm.
Instead warn the user that some of the faces have been unclassified and not used for solids creation.
Adjustment of the test cases.
Test cases for the issue.
All library-specific macros for defining export / import properties of symbols on Windows (like Standard_API, __Draw_API, _math_API etc.) are eliminated.
Common macro Standard_EXPORT is used in all places where it is necessary.
New macro OCCT_STATIC_BUILD is defined for disabling Standard_EXPORT, to be used instead of HAVE_NO_DLL, though the latter is still supported as well (for compatibility).
To allow building OCCT in static mode on Windows after these changes:
- Files OSD_WNT_1.hxx and OSD_WNT_BREAK.hxx are removed; useful declarations are moved to OSD_WNT.hxx
- In the class IVtkVTK_ShapeData, static fields ARRNAME_MESH_TYPES and ARRNAME_SUBSHAPE_IDS are converted to static inline functions
- Global array ChoixRef defined in IntImp_ComputeTangence.cxx is converted to static function returning element of the array by index
- Unused class Quantity_Convert is removed (it had static field accessed by inline method)
- Struct Approx_Data defined in the same way in BRepApprox_Approx.hxx and GeomInt_WLApprox.hxx is made private member of these classes to avoid name clash
- Some C++ files producing no object code are removed
- In NCollection_EBTree.hxx and StdLPersistent_Collectio.hxx, definition of template virtual method is moved to class definition to avoid MSVC linker warnings on unused symbols
The following unused declarations have been removed:
Aspect_TypeOfPrimitive, Aspect_TypeOfLayer, Aspect_TypeOfEdge,
Aspect_TypeOfDrawMode, Aspect_TypeOfConstraint,
Aspect_DriverDefinitionError, Aspect_BadAccess.
Graphic3d_AspectFillArea3d has been extended by new property ::ShadingModel(),
which is set to Graphic3d_TOSM_DEFAULT by default.
The new API allows assigning Shading Model to specific Primitive Array groups
instead of entire Viewer, which was the only possibility before.
Graphic3d_TypeOfShadingModel has been extended with Graphic3d_TOSM_DEFAULT value
meaining that Shading Model defined as default for the Viewer should be used.
Graphic3d_TOSM_NONE has been renamed to Graphic3d_TOSM_UNLIT.
Documentation of Shading Models has been improved by more details.
V3d_TypeOfShadingModel enumeration has been merged into Graphic3d_TypeOfShadingModel
avoiding duplicated definitions and confusion.
Old values has been left for compatibility with old code and can be marked deprecated in future.
Draw Harness command vaspects has been extended by new argument -setShadingModel
for testing Shading Models assigned to entire objects.
OpenGl_SetOfShaderPrograms now holds an array of Shading Models.
OpenGl_ShaderManager interface has been modified and now requires enumeration as input
in several places where Boolean flags have been used previously
(methods ::BindFaceProgram(), ::BindLineProgram(), ::BindMarkerProgram()).
OpenGl_Workspace now defines default (undefined) OpenGl_AspectFace as Graphic3d_TOSM_UNLIT
to simplify indication of primitive groups with undefined Fill Area aspects,
and so that Graphic3d_TOSM_UNLIT set as default Shading Model will not make artifacts on Lines and Markers.
AIS_Manipulator::Axis::Compute() - added missing initialization of Fill Area aspects (leading to undefined behavior).
Now, bounded IntPatch_Points are found in case when starting points are used in intersection algorithm. Before the fix, these points were not looked for (even).
The usage of *BRepAlgo_Section* has been replaced with the usage of *BRepAlgoAPI_Section* in *BRepProj_Projection* algorithm.
The TODO statements have been removed from the failing test case in the "prj" grid as they are working correctly now.
The following changes have been made to improve the performance *BRepAlgoAPI_Section*:
1. Revision of the *IntPolyh_Intersection* class to avoid repeated calculation of the deflection of the same triangulation.
2. Small revision of the Edge/Face intersection algorithm to perform Extrema computation on the whole intersection range of the edge instead of discrete ranges.
3. Implementation of the extrema computation for the Circle and Sphere.
4. Correct computation of the parameter of the point on the Circle.
Before the fix, BRepAdaptor_CompCurve considered the input wire to be periodic with period LastParameter()-FirstParameter().
Now, method IsPeriodic will always return FALSE because it is impossible to obtain correspondence between the members of BRepAdaptor_CompCurve class and its periodicity status.
New behavior has been documented in upgrade-guide.
1. Implementation of the *Generated* method for the algorithms in Boolean Component.
In terms of these algorithms the shape from the arguments can have Generated shapes only if these new shapes have been obtained as a result of pure intersection (not overlapping) of this shape with any other shapes from arguments.
Thus, the Generated shapes are always:
* VERTICES created from the intersection points and may be Generated from edges and faces only;
* EDGES created from the intersection edges and may be Generated from faces only.
So, only EDGES and FACES could have information about Generated shapes. For all other types of shapes the list of Generated shapes will be empty.
2. Optimization and simplification of the Modified and IsDeleted methods based on the correct filling of the BOPAlgo_BuilderShape::myImagesResult map.
3. Provide history of unification of the solids in the CellsBuilder algorithm.
4. Update of the documentation of Boolean Operations User guide with new chapter "History Information" describing rules for filling history for operations in Boolean Component.
5. Test cases for the issue. New grid "history" has been added into "boolean" category.
Graphic3d_CLight is now defined as a class inheriting Standard_Transient,
so that it's fields now should be accessed through methods.
Graphic3d_CLight::IsEnabled() - new property allowing to disable light source everywhere.
Confusing alias OpenGl_Light has been removed.
Graphic3d_CLight::SetAttenuation() - the upper limit 1.0 of attenuation factors has been removed
since it contradicts to OpenGL specs and does not make sense.
Graphic3d_ZLayerSettings::Lights() - light sources list is now property of ZLayer.
When defined, it overrides light sources defined for View/Viewer.
New class Graphic3d_LightSet has been defined to define a set of light sources.
V3d_Light - removed obsolete interface for debug drawing lights sources.
V3d_Light is now an alias to Graphic3d_CLight.
V3d_TypeOfLight is now defined as a typedef to Graphic3d_TypeOfLightSource.
Prevent modification of the input shapes in destructive mode in case their sub-shapes have not been modified:
1. Prevent edge splitting for the pave blocks with old vertices if it is possible to use the existing edge (*BOPAlgo_PaveFiller::MakeSplitEdges*);
2. Prevent creation of the new containers (WIRES/SHELLS/COMPSOLIDS) if non of its parts have been modified (*BOPAlgo_Builder::FillImagesContainer*);
3. Prevent creation of the new face if non of its wires have been modified (*BOPAlgo_Builder::FillImagesFaces*);
4. If possible, use the original face to be the representative for the group of SD faces (*BOPAlgo_Builder::FillSameDomainFaces*).
Cosmetic changes:
1. Documentation of the *BOPAlgo_Builder* class.
2. Making simple methods of the *BOPAlgo_Builder* class inline.
3. Getting rid of the *BOPAlgo_Builder::mySplits* field as it is excessive. *BOPAlgo_Builder::myImages* can be used instead.
3. Moving the Check Inverted option from *BOPAlgo_Options* to *BOPAlgo_Builder*.
Test cases for the issue.
Adjustment of the test case to their current behavior.
Test case *blend/complex/H2* has been deleted as duplicate of the test case *blend/simple/Z1*.

This patch turns off some not needed modes of fix in the called ShapeFix_Face algorithm.
It stores pcurves on planes in the edges to avoid repeated computation of the same pcurves many times (it is done only when SafeInputMode is false).
It avoids unnecessary replace/apply actions in the modification context.
It removes the code that makes decomposition of surface of the face on several faces.
The new command buildpcurvesonplane has been added, which builds and stores pcurves of edges on planar faces. This is useful for investigations how presence of pcurves on planes influence performance of algorithms.
Make drawing of dimension line in snowflake test independent on the order of vertices in the result.
Command testfile is improved to be more usable by developers for checking data files used by the new test cases before their integration to the test data base:
1. Do not check and do not report problems found in the repo when checking new files -- this check is done only when argument is "-check"
2. Can check a file located in a directory listed in CSF_TestDataPath as new one without it being considered as already in the data base
3. For new BREP files, reports warning if the file contains triangulation, suggesting that it can be removed to minimize the size
4. Can identify the same (by content) file in the data base for the new files in DOS encoding (less than 1 MB)
5. Can detect duplicates among the input files
6. Outputs result in more clear form
7. When loading STL files, uses option "triangulation" to be efficient
Automated Testing System guide is updated to describe command testfile.
Added test demo testsystem testfile
Documentation is added in a new "Inspector" page of "User Guides".
Inspector plugins has some improvements by the documentation needs.
New DRAW scripts are implemented for 'tinspector' command.
Upgrade Guide is updated to describe:
- Removal of typedefs to double in Quantity and V3d
- Removal of support of orientation in classes BRepTools_ReShape and ShapeBuild_ReShape
- Removal of AIS methods taking/returning Quantity_NameOfColor instead of Quantity_Color
- Removal of active texture state from OpenGl_Workspace
New helper script svgdiff.bat is added in adm folder.
It can be used for enabling visual diff for SVG images in TortouseGit; see Git guide for details.
When updating files msvc.bat and draw.bat/sh in the root folder by copying template from adm/templates, procedure genproj will give a warning (unless the files are already the same); if the target file is newer, its copy is saved with additional extension .bak.
STL Reader and Writer tools have been refactored to improve performance and usability:
- Basic reading of STL file is separated to abstract class RWStl_Reader which is not bound to particular data structures; the target data model can be bound via inheritance.
- RWStl package uses class Poly_Triangulation to represent triangular mesh.
- Obsolete data structures and tools (packages StlMesh and StlTransfer) are removed.
AIS_Shape and AIS_ColoredShape now computes Shaded presentation
with UV coordinates if texture mapping is enabled in Drawer.
OpenGl_Context::SetTextureMatrix() - fixed inconsistent handling
of texture cooridnates translation vector.
vtexture command has been extended to handle new arguments:
* -trsfTrans, -trsfScale, -trsfAngle defining transformation matrix
* -setFilter, -setAnisoFilter to setup texture filtering
Added support of Visual Studio 2017 (15) in CMake build procedure.
CMake 3.7.2 or above is required to generate projects for VS 2017.
Since version of compiler and toolset remained at 14 (now they are 14.1), and they use the same run-time, the same third-party products as for VS 2015 (14) can be used.
Also the name of the folder for installation of OCCT binaries in OCCT-standard layout (default on Windows) remains "vc14".
Support of Visual Studio 2017 is added in genproj generator and relevant environment, with format specifier "vc141".
The syntax of the genproj command is revised:
- UWP is considered as separate platform ("uwp" alternative to "wnt"), not part of IDE specification
- Option "IDE" is renamed to "Format"
- Obsolete name of local variable "aWokStation" is replaced by equivalent "theFormat"
In environment scripts, additional variables are defined (derived from VCVER, see adm/vcver.bat):
- VCLIB defines name of the subdirectory specific to VS version; it is the same as VCVER except that for VCVER=vc141 VCLIB=vc14 and for VCVER=141-uwp VCLIB=vc14-uwp
- VCFMT is VCVER without optional suffix "-uwp"
- VCPROP is "NativeDesktop" for normal builds or "Universal" for UWP builds
Command genconf is amended to:
- Detect presence of VS 2017 (separately for desktop and UWP)
- Use only two first digits after "vc" in format specification for search of third-party libs
- Have more space in user interface for VS specification
All supported variants of VCVER variable are documented in dev guides / buiding / msvc
Quantity_ColorRGBA - added method SetValues().
Image_PixMap::PixelColor() now returns Quantity_ColorRGBA instead of Quantity_Color.
Image_PixMap::SetPixelColor() now takes Quantity_ColorRGBA instead of NCollection_Vec4<float>.
Image_Diff has been improved to support Image_Format_Gray.
Image_Diff::SaveDiffImage() now saves image difference
in Image_Format_Gray format to reduce size of image file.
Image_Diff now uses TColStd_HPackedMapOfInteger instead of
TColStd_MapOfInteger with manual memory allocation.
Use of Cotire tool is introduced for acceleration of CMake builds, by usage of precompiled headers.
CMake option BUILD_USE_PCH is added to enable / disable use of precompiled headers
When precompiled headers are used, additional compiler macros are defined globally in the build system to avoid problems due to different order of included files:
- NOMINMAX is defined on Windows to prevent defining "min" and "max" as macros by windows.h
- STRSAFE_NO_DEPRECATE and _SCL_SECURE_NO_WARNINGS are defined on Windows to prevent declaring functions of standard C library as deprecated by #pragma, and other warnings in system headers
- GL_GLEXT_LEGACY and GLX_GLEXT_LEGACY are defined to ensure that only OCCT's own glext.h is used
- __STDC_FORMAT_MACROS is defined to have standard C print format macros always defined
Code is corrected to avoid conflicts with system headers and in case of compiling together as unity builds (partially):
- Some locally defined variables in TKV3d, TKHLR are renamed to be unique
- Duplicated definitions of macros and global functions are eliminated in TKSTEP
- Useless header WNT_UInt.hxx is removed
- Usage of local variables conflicting with X11 macro is avoided in Draw_Viewer.cxx
- Local variables in AIS_ConcentricRelation.cxx are renamed to avoid conflict with macros defined in windows.h
- HXX files containing code are renamed to PXX or merged with corresponding CXX files.
IVtkTools classes are corrected to avoid compiler warnings disabled in non-PCH builds by inclusion of VTK headers.
Useless pragmas disabling warnings on MSVC are removed
'BRepTools_History' history was implemented for algorithm
'ShapeUpgrade_UnifySameDomain'.
The history of the changing of the initial shape was corrected to consider all
shapes created by the algorithm as modified shapes instead of generated ones.
The old history interface was replaced by the new one:
- to get the modified shapes use: History()->Modified();
- to check if the shapes has been deleted use: History()->IsRemoved().
Type 'BRepTools_ReShape' was extended to:
- support the 'BRepTools_History' history;
- merge several shapes to a single shape that
the history of the merged shapes is presented by equal ways.
Type 'ShapeBuild_ReShape' was changed to support 'BRepTools_History' history.
